STEP 1: Create 3 small triangles on the top of the head. Position one toward the top back and the other two slightly off

center. This will allow the color to peak through a classic bob and change its appearance when the part is shifted.

STEP 2: Alternate Formulas 2 and 3 within the triangles. First, create two back-to-back slices of Formula 2, then repeat with Formula 3. For some slices, apply formula from scalp to ends; for a few others, meld both formulas within one foil. Pivot through all 3 triangles in this manner.
